Selling the
Storage Edition for Oracle
November 2000
The Need
Key Customer Concerns
Continuous availability (24x7) of
mission-critical Oracle databases
• How much does downtime cost your business in
regard to lost user productivity, reduced company
revenue, and poor customer service?
Faster access to data
• Are you using file systems or raw disk partitions
to store Oracle data?
Easier management of increasing data
• Do your DBAs have to learn how to manage raw
disk partitions to gain database performance?
Building the Solution
What is the customer using, and how does
this product fit into their installation?
• HP-UX 11.0
– New Installations
– Upgrading OS
• Oracle7.3 or later (inclusive of Oracle 8i)
– Upgrading database
– Database can withstand some downtime

New Feature Overview
Support for Asynchronous I/O
• Raw device performance
• Up to 160% faster than buffered I/O file systems
• Allows for parallel updates to datafiles
Storage Checkpoints
• Enable Block-Level Incremental Backup
• Enable Storage Rollback for immediate “point-intime” recovery from on-disk images
Key Differentiator:
VERITAS Storage Checkpoints
Point-in-time snapshot of database
Storage Checkpoints maintain changed
data blocks as database is being
updated
• Uses efficient copy-on-write technique
• No post-processing needed to scan for
changed data blocks
Benefits of Storage Checkpoints
Storage Rollback:
• VxDBA utility manages Storage
Checkpoints for faster database
recoverability from on-disk backup image
• Protects from logical errors
• What-if analysis
Block-Level Incremental Backup:
• NetBackup manages Storage Checkpoints
and extracts only the changed blocks
• Virtually eliminates database backup
window
Storage Rollback
Storage Checkpoints are on-disk backup
images
• Consistent, stable images of a file system at a
particular point in time
Storage Rollback is “restore” from the ondisk backup images or Storage
Checkpoints
• Copies before-images of data blocks back to the
live file system
• Restores without going to tapes
Storage Rollback
Recovery from Storage Checkpoints
=
Simply write back changed (blue) blocks
to previous state and then apply redo logs
to bring database to desired point in time
Block-Level Incremental Backup
Back up only changed data blocks!
Increased data availability
• Virtually eliminates database backup windows
• Allows more frequent backup schedules
Backups contains up-to-date data
Enhanced performance
• Significantly lowers CPU and network resource drain
during backup
• Faster recovery from backups (less redo logs to apply)
Requires NetBackup Server engine and
database server to be backed up to be a
NetBackup client
